EXPAL'DED METAL.

Original application filed April 16, 1921, Serial No. 461,868. Divided and this application led August 22,

1922. Serial No. 583,61.

To all 'whom t 'may concern.'

Be it known that we, HARRY lvl. 'Navona and ARTHUR J. Townsmen, citizens of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented a newand useful Improvement in Expanded Metal, of which the following is a specifications Y y The invention relates lto expanded metal made of sheets, strips or the like, of the diamond mesh type in which the mesh is continuous and is composed of corrugated bonds and straight strands or bars; and the object of the improvement is to decrease the thickness of the expanded portion of the sheet and increase the truss strength'of the same, which is 'accomplished by locating the bonds and the strands in the same plane.

The particular type of diamond mesh with which the present invention is concerned has always been produced with the alternate bonds in different planes, so that the expanded sheet has been markedby .distinct series of transverse eorrugations,1 with alternate transverse rows of bonds located inthe bottom of the corrugations and the intervening transverse rows of bonds being located at the crests ofthe corrugations.

In the present improvement of this' type of diamond mesh expanded metal, all the corrugated bonds and all the laterally inclined strands are located in the same plane, as shown in the accompanying drawings forming part hereoin which- Figure 1 is a plan view of the improved expanded metal, showing e. series of shallow ribs located between zones of expanded mesh;

Fig. 2, a cross section of the same on line 2 2, Fig. l; and t Fig. 3, a longitudinal section of the seme on line 3-1-3, Fig. l.

Similar numerals refer to like parte throughout the drawings.

The ad'acentrows of bonds 4 and 4' are corrufnited in reversedirection, and are so positioned that the angles of one row of the corrugations are in the same plane with the sides or edges of the other corrugations,`,so that the bonds as a whole are located in the same plane; and the strands 5 and 5' be'- 'tween .the Vbonds are laterally inclined like the connected portion of the bonds and are formed straight without an twisting between' therbonds, so. as to he in the same plane therewith.

concrete applied to or built upon it, until it becomes set and hardened sufficiently to sustain itself; and in the improved expanded metal gives greater strength to a finished wall in which it may beused as a reinforcement.

The improved form of expanded mesh may he made in zones between unexpanded strips of a sheet, and the nonexpanded strips may be made in the form of beads or ribs 6 as shown in the drawings; and the improved product may be made by the method and apparatus illustrated and described in our pending application for Letters Patent, filed April 16, 1921, Serial No. 461,806, of which the present application is a division. By this method and apparatus the strands are Astretched or elongated so that the expanded zones are not shortened and the ribs are not contracted.

Weclaiin:

1. Expanded sheet metal having continuous diamond meshes with reversely corru` gated bonds and laterally inclined strands in the same lane.

2. Expan ed sheet metal having continuvous diamond meshes with corrugated bonds' and laterally inclined straight strands in the same plane. v

3, Metal sheets having longitudinal expanded zones and intervening nonexpanded strips, the zones having continuous diamond meshes formed therein with corrugated bonds and stretched strands, and the strips havin non-contracted ribs formed therein. 4.- etal sheets having longitudinal 'eirpanded'i'ones and intervening nonex anded strips, the zones having continuous diamond meshesv formed therein with corrugated bonds and'stretched strands in the same plane. and thel strips having non-contracted ribs formed therein.
